Cleaning and Sanitizing

Why it Matters

• Prevents cross-contamination and foodborne illnesses.
• Maintains compliance with health regulations (for businesses).
• Preserves reputation and customer trust.

‍

Definitions

• Cleaning: Removal of dirt, debris, and residues using soap/detergent.
• Sanitizing: Reducing pathogens to safe levels using heat or chemicals.
• Example: Wiping a counter (cleaning) vs. applying a bleach solution (sanitizing).

‍

Home Kitchens

Steps for Effectiveness:

1. Clean First: Use hot, soapy water on surfaces, utensils, and cutting boards.
2. Sanitize: Apply EPA-approved sanitizer (e.g., 1 tbsp bleach per gallon of water). Let air dry.
3. Frequency: After handling raw meat, eggs, or spills; daily for high-touch areas.

Tools & Products:

• Dish soap, bleach, commercial sanitizing sprays.
• Color-coded cloths (e.g., red for raw meat areas).

Common Mistakes:

• Using vinegar as a sanitizer (not EPA-approved).
• Not air-drying sanitized surfaces.

‍

Restaurants

Regulations & Protocols:

• Dishwashing:
  • Manual: Three-compartment sink (wash, rinse, sanitize).
  • Machine: Ensure water reaches 165°F (74°C) for heat sanitizing.
• Surface Sanitizing: Use quaternary ammonium or chlorine solutions (test strips verify concentration).
• Frequency: Every 2–4 hours, after tasks, and at closing.

Best Practices:

• Label sanitizer bottles with contents and dilution instructions.
• Train staff on contact time (e.g., 30 seconds for bleach solutions).

Case Study: A restaurant failed inspection due to improper sanitizer concentration. Solution: Daily checks with test strips.

‍

Catering

Mobile Challenges & Solutions:

• Portable Sanitation: Use alcohol-based wipes or pre-moistened sanitizing cloths.
• Equipment: Pre-sanitize containers and utensils before transport.
• Waste Management: Seal trash bins and dispose of waste off-site.

Best Practices:

• Pack disposable gloves and single-use utensils for events.
• Use insulated containers to keep food at safe temps, reducing spoilage risk.

Example: A caterer avoided cross-contamination by using separate cutting boards for raw and ready-to-eat foods.

‍

Common Mistakes & Solutions

• Mistake: Reusing the same cloth everywhere
  • Solution: Use color-coded cloths for different zones.

• Mistake: Skipping sanitizer contact time
  • Solution: Set a timer (e.g., 1 minute for bleach).

• Mistake: Storing chemicals near food
  • Solution: Designate a locked storage area.

‍

Safety Tips

• Chemical Handling: Wear gloves and goggles; never mix cleaners.
• Tools: Replace sponges weekly; sanitize reusable cloths in hot water.
• Personal Hygiene: Wash hands before/after cleaning.

‍

Conclusion

• Home: Clean and sanitize proactively, especially after raw food prep.
• Restaurants: Follow health codes rigorously—document processes.
• Catering: Adapt to mobile challenges with pre-sanitized gear and disposables.

‍

Key Takeaway: Sanitizing is only effective after thorough cleaning. Prioritize both to ensure safety in every setting.
